Alfred C. Kinsey: Contributions to American Sexuality

Kinsey's Homosexuality Statistics Shocked America

Kinsey's findings on homosexuality also shocked the American public. He reported that a third of American males and 13 percent of American females claimed to have had at least one same-sex orgasmic experience by age 45.

Furthermore, approximately 10 percent of the males admitted to having been predominantly homosexual for at least three years between the ages of 16 and 55, and four percent of white males described themselves as exclusively homosexual. Kinsey's research refuted the widely held notion that heterosexuality and homosexuality are exclusive forms of behavior.

His study found that more than 90 percent of white males and 62 percent of females admitted having engaged in this behavior.
